The equipment information storage unit EM that operates as the storage unit IU and operates as the regular equipment information storage unit IU before switching is operated as the emergency equipment information storage unit IF after switching.
As a result, the updated equipment information CEI stored in the emergency equipment information storage unit IF is referred to as the equipment information EI stored in the regular equipment information storage unit IU after switching. That is, the monitoring control server device MSV refers to the updated equipment information CEI stored in the emergency equipment information storage unit IF before switching as the equipment information EI, and acquires the monitoring information MI from the equipment EQ. Further, the system board server device CSV refers to the updated equipment information CEI stored in the emergency equipment information storage unit IF before switching as the equipment information EI after switching, and acquires the monitoring information MI from the equipment EQ.

In the above description, the maintenance function starts DB switching to the monitoring control server device MSV and the system board server device CSV in response to the completion of storage (update) of the update equipment information CEI in the emergency equipment information storage unit IF. The case of transmitting information has been described, but the present invention is not limited to this. The DB switching start information may be transmitted according to the operation of the operator OPT. In this case, the monitoring and control server device MSV and the system board server device CSV are transmitted to the emergency equipment information storage unit IF when the storage of the updated equipment information CEI is completed and in response to the operation of the operator OPT. When the DB switching start information is received, the operation of the normal equipment information storage unit IU and the emergency equipment information storage unit IF is switched.

Further, in the centralized monitoring control system 1 of the present embodiment, the equipment information storage unit EM is a regular equipment information storage unit (in one example of the present embodiment, the regular equipment information storage unit IU) and an emergency equipment information storage unit (this). In one example of the embodiment, it has an emergency equipment information storage unit IF).
The maintenance virtual server system transmits the updated equipment information CEI to the emergency equipment information storage unit IF of the server device that operates on standby among the server devices owned by the server base S. The standby operation of the server device will be described later.

[About the operation of the maintenance function]
The details of the operation of the maintenance function will be described below with reference to the figure.
FIG. 7 is a flow chart showing an example of the operation of the maintenance server device KSV of the first embodiment.
The maintenance interface function of the maintenance server device KSV (maintenance virtual HMI server system) acquires the update operation information REI from the maintenance desk thin client NCT provided in each control center C (step S510). The maintenance interface function supplies the acquired update operation information REI to the maintenance function of the maintenance server device KSV (maintenance virtual server system) (step S520). The maintenance function acquires the update operation information REI from the maintenance interface function (step S530). The maintenance function generates update equipment information CEI based on the acquired update operation information REI (step S540). The maintenance function supplies the generated update equipment information CEI to the monitoring control server device MSV and the system board server device CSV (step S570). The monitoring and control server device MSV stores the acquired update equipment information CEI in the equipment information storage unit EM (emergency equipment information storage unit IF) included in the monitoring and control server device MSV (step S580). The system board server device CSV stores the acquired update equipment information CEI in the equipment information storage unit EM (emergency equipment information storage unit IF) included in the system board server device CSV (step S590).
The maintenance function stores the update equipment information CEI in the monitoring control server device MSV and the system board server device CSV, and then supplies the DB switching start information to the maintenance interface function (step S600). The maintenance interface function acquires DB switching start information from the maintenance function (step S610). The maintenance interface function transmits the acquired DB switching start information to the monitoring control server device MSV in the standby operation and the system board server device CSV in the standby operation (step S620). The maintenance interface function acquires, for example, information indicating the operating status of the monitoring control server device MSV and the system board server device CSV via the maintenance LAN. Further, the maintenance interface function transmits DB switching start information to the standby operation server device based on the acquired information indicating the operating state of the monitoring control server device MSV and the system board server device CSV. The monitoring control server device MSV switches the operation of the equipment information storage unit EM in response to receiving the DB switching start information (step S630). Specifically, the equipment information storage unit EM included in the monitoring control server device MSV operates between the regular equipment information storage unit IU and the emergency equipment information storage unit IF in response to receiving the DB switching start information. Can be switched. Further, the system board server device CSV switches the operation of the equipment information storage unit EM in response to receiving the DB switching start information. (Step S640). Specifically, the equipment information storage unit EM included in the system board server device CSV operates between the regular equipment information storage unit IU and the emergency equipment information storage unit IF in response to receiving the DB switching start information. Can be switched. As a result, the equipment information EI is equivalent in the plurality of monitoring and control server device MSVs and the plurality of system board server devices CSV included in the centralized monitoring and control system 1.

The centralized monitoring and control system 1 of the present embodiment corresponds to the equipment information of the equipment EQ referred to by the server group 10 of each server base S by the maintenance function. In the present embodiment, one monitoring and control server device operates as a regular operation and the remaining two units operate as a standby. By always equivalent the equipment information of the three monitoring and control server devices in this way, 3 Even if any one of the server bases S is changed to regular use, the equipment EQ can be monitored and controlled.
A monitoring and control system is arranged for each control station C. Compared to a configuration in which each has an equipment information storage unit, the centralized monitoring and control system 1 of the present embodiment can reduce the number of devices constituting the equipment information storage unit. Therefore, it is possible to reduce the equipment cost and the operation cost related to the device for storing the equipment information EI.
Further, according to the centralized monitoring control system 1 of the present embodiment, the maintenance server device KSV updates the equipment information EI of each monitoring control server device MSV and each system board server device CSV via the maintenance LAN. As a result, the centralized monitoring and control system 1 of the present embodiment can reduce the number of devices to be updated as compared with the case where the devices for updating the equipment information EI are provided for each control station C. Therefore, the equipment information EI can be updated. It is possible to reduce the equipment cost and operating cost related to the equipment for updating.

[Synchronization between servers]
Here, the centralized monitoring and control system 1 is configured so that the substation T (equipment EQ) to be monitored and controlled can be monitored and controlled by the three server bases S. In order for all of the monitoring and control server device MSVs of the three server bases S to enable monitoring and control of the equipment EQ of the centralized monitoring and control system 1, the equipment information EI of the equipment EQ to be monitored and controlled is maintained and the equipment information EI is maintained. In addition to synchronizing (equivalent) by the maintenance interface function, it is preferable to synchronize (equivalent) the information of the monitoring information MI. In this example, the monitoring control server device MSVA operates as a regular device (hereinafter, regular operation), and the monitoring control server device MSVB and the monitoring control server device MSVC operate as a standby device (hereinafter, standby operation) in normal times. The case will be described.
The monitoring control function of the monitoring control server device MSV that operates regularly (in this example, the monitoring control server device MSVA) is the monitoring control server device MSV that operates in standby mode (in this example, the monitoring control server device MSVB and the monitoring control server device). The monitoring information MI is transmitted to MSVC). The monitoring control server device MSVB and the monitoring control server device MSVC receive the monitoring information MI from the monitoring control server device MSVA and store the monitoring information MI in a storage unit (not shown). As a result, the centralized monitoring and control system 1 synchronizes the monitoring information MI of the monitoring and control server device MSV provided in each server base S by the monitoring and control function.
Further, the monitoring control server device MSV has a status monitoring function. The status monitoring function is a function for detecting a communication failure between the own device (monitoring control server device MSV) and another monitoring control server device MSV. In this example, the condition monitoring function is a function of detecting whether or not a communication failure has occurred in the wide area network hN. Here, there is a case where the state monitoring function detects a communication failure and the operation mode of the detected monitoring control server device MSV is a standby operation. In this case, the condition monitoring function shifts the operation mode of the monitoring control server device MSV to the normal operation. That is, when a communication failure has occurred in the wide area network hN and the functions of each monitoring and control server device MSV have not been lost, the operation modes of the monitoring and control server device MSV included in the centralized monitoring and control system 1 are all in normal operation. Is. The loss of the function of the monitoring and control server device MSV means that the monitoring and control server device MSV cannot perform at least one of the monitoring and control of the equipment EQ to be monitored and controlled due to a server device failure or the like.
The condition monitoring function is a function for detecting whether or not the function of the monitoring control server device MSV for normal operation is lost. Here, the state monitoring function of the standby operation monitoring control server device MSV may detect that the function of the normal operation monitoring control server device MSV is lost. In this case, in response to the detection that the function of the monitoring control server device MSV of the normal operation is lost, the operation mode of one of the monitoring control server device MSVs of the standby operation is the regular operation. Transition to operation.

The operation mode at startup is preset in the monitoring control server device MSV. In the following description, the setting of the operation mode at startup will be described as the initial setting. In this example, the monitoring control server device MSVA, the monitoring control server device MSVB, and the monitoring control server device MSVC each have the monitoring control server device MSVA in regular operation, and the monitoring control server device MSVB and the monitoring control server device MSVC in standby operation. Initial settings to be performed are set in advance. The monitoring control server device MSVA, the monitoring control server device MSVB, and the monitoring control server device MSVC operate by selecting the operation mode based on the initial settings when the own device is started or restarted.
Further, the monitoring control server device MSV is prioritized in advance for each monitoring control server device MSV. In this example, the monitoring and control server device MSVA has a higher priority than the monitoring and control server device MSVB. Further, the monitoring control server device MSVB has a higher priority than the monitoring control server device MSVC. The status monitoring function shifts the operation mode of the monitoring control server device MSV having a higher priority to the normal operation among the monitoring control server device MSVs that have not lost the function of the monitoring control server device MSV. Therefore, when the function of the monitoring control server device MSVA is lost, the monitoring control server device MSVB operates regularly and the monitoring control server device MSVC operates in standby mode. Further, when the functions of the monitoring control server device MSVA and the monitoring control server device MSVB are lost, the monitoring control server device MSVC operates regularly.

[About the operation of synchronization between servers: Stopping the operation of the regular server]
Hereinafter, synchronization of the monitoring information MI of the centralized monitoring control system 1 will be described with reference to the drawings.
FIG. 8 is a first flow chart showing an example of the operation of the monitoring control server device MSV of the first embodiment.
The monitoring and control server device MSV determines whether the own device is in the normal operation or the standby operation at all times or at predetermined time intervals (step S710). When the monitoring control server device MSV determines that the own device is in normal operation (step S710; YES), the monitoring control server device MSV transmits the monitoring information MI to the monitoring control server device MSV which is another monitoring control server device MSV and operates in standby mode. (Step S720). When the monitoring control server device MSV determines that the own device is in standby operation (step S710; NO), whether or not the operation of the monitoring control server device MSV, which has one higher priority than the own device, has changed from the normal operation to the stop operation. Is detected (step S730). If the monitoring control server device MSV in the standby operation has not detected that the monitoring control server device MSV, which has one higher priority than the own device, has changed from the normal operation to the stop (step S730; NO), the process proceeds to step S710. Proceed. Further, when the monitoring control server device MSV of the standby operation detects that the operation of the monitoring control server device MSV having one higher priority than the own device has changed from the normal operation to the stop (step S730; YES), the standby operation is started. The operation mode is changed to the normal operation (step S740).

[Synchronization between servers: Communication failure occurred]
Hereinafter, synchronization of the monitoring information MI of the centralized monitoring control system 1 will be described with reference to the drawings.
FIG. 9 is a second flow chart showing an example of the operation of the monitoring control server device MSV of the first embodiment.
The monitoring and control server device MSV determines whether the own device is in the normal operation or the standby operation at all times or at predetermined time intervals (step S410). When the monitoring control server device MSV determines that the own device is in normal operation (step S410; YES), the monitoring control server device MSV transmits the monitoring information MI to the monitoring control server device MSV which is another monitoring control server device MSV and operates in standby mode. (Step S420). When the monitoring control server device MSV determines that the own device is in standby operation (step S410; NO), it detects whether or not a communication failure has occurred (step S430). If the standby operation monitoring control server device MSV does not detect that a communication failure has occurred in the network (in this example, the wide area network hN) (step S430; NO), the process proceeds to step S710. Further, when the monitoring control server device MSV for the standby operation detects that a communication failure has occurred in the wide area network hN (step S430; YES), the operation mode is changed from the standby operation to the normal operation (step S440). ..

In addition, the monitoring control server device MSV for normal operation is replaced with a configuration in which monitoring information MI is transmitted to all the monitoring control server device MSV for standby operation, and at least a part of the monitoring control server device MSV for standby operation is monitored and controlled. The configuration may be such that the monitoring information MI is transmitted to the server device MSV. Of the standby operation monitoring control server device MSVs, at least a part of the monitoring control server device MSVs is, for example, the monitoring control server device provided in the control center C adjacent to the control center C including the normal operation monitoring control server device MSV. It is MSV.

As with the monitoring and control server device MSV, the system board server device CSV may also have a configuration for regular operation and standby operation. That is, in order for all of the system board server device CSVs of the three server bases S to be able to monitor the equipment EQ of the centralized monitoring and control system 1, the equipment information EI of the equipment EQ to be monitored has a maintenance function and a maintenance function. In addition to synchronizing (equivalent) by the maintenance interface function, it is preferable to synchronize (equivalent) the information of the monitoring information MI. In this example, a case where the system board server device CSVA normally operates and the system board server device CSVB and the system board server device CSVC operate in standby mode will be described.
The system board display function of the system board server device CSV (in this example, the system board server device CSV) that operates regularly is the system board server device CSV (system board server device CSVB in this example, and the system board server) that operates in standby mode. The monitoring information MI is transmitted to the device CSV). The system board server device CSVB and the system board server device CSVC receive the monitoring information MI from the system board server device CSVA, and store the monitoring information MI in a storage unit (not shown). As a result, the centralized monitoring and control system 1 synchronizes the monitoring information MI of the system board server device CSV provided in each server base S by the system board display function.
Further, the system board server device CSV has a status monitoring function. The status monitoring function is a function for detecting a communication failure between the own device (system board server device CSV) and another system board server device CSV. In this example, the condition monitoring function is a function of detecting whether or not a communication failure has occurred in the wide area network hN. Here, there is a case where the state monitoring function detects a communication failure and the operation mode of the detected system board server device CSV is a standby operation. In this case, the status monitoring function shifts the operation mode of the system board server device CSV to the normal operation. That is, when a communication failure has occurred in the wide area network hN and the functions of each system board server device CSV have not been lost, the operation modes of the system board server device CSV included in the centralized monitoring and control system 1 are all in normal operation. Is. The loss of the function of the system board server device CSV means that the system board server device CSV cannot monitor the equipment EQ to be monitored due to a server device failure or the like.
Further, the condition monitoring function is a function of detecting whether or not the function of the system board server device CSV in normal operation is lost. Here, the state monitoring function of the standby operation system board server device CSV may detect that the function of the regular operation system board server device CSV is lost. In this case, in response to the detection that the function of the system board server device CSV of the normal operation is lost, the operation mode of one of the system board server device CSVs of the standby operation is the regular operation. Transition to operation.

Further, the system board server device CSV included in the centralized monitoring and control system 1 may also have initial settings set in advance in the same manner as the monitoring and control server device MSV. In this example, the system board server device CSVB, the system board server device CSVB, and the system board server device CSVC each have the system board server device CSVA in regular operation, and the system board server device CSVB and the system board server device CSVC in standby operation. Initial settings to be performed are set in advance. The system board server device CSVA, the system board server device CSVB, and the system board server device CSVC operate by selecting the operation mode based on the initial settings when the own device is started or restarted.
Further, the system board server device CSV may be prioritized for each system board server device CSV. In this example, the system board server device CSVA has a higher priority than the system board server device CSVB. Further, the system board server device CSVB has a higher priority than the system board server device CSVC. The status monitoring function shifts the operation mode of the system board server device CSV having a higher priority to the normal operation among the system board server device CSVs for which the functions of the system board server device CSV have not been lost. Therefore, when the function of the system board server device CSVA is lost, the system board server device CSVB operates regularly and the system board server device CSVC operates in standby mode. Further, when the functions of the system board server device CSVA and the system board server device CSVB are lost, the system board server device CSVC operates regularly.

According to the centralized monitoring control system 1 of the present embodiment, the monitoring control function synchronizes (equivalents) the monitoring information MI of the monitoring control server device MSV included in the centralized monitoring control system 1.
As a result, the centralized monitoring and control system 1 of the present embodiment transitions the normal operation and the standby operation even if a problem occurs in any of the monitoring and control server device MSVs provided in each server base S. By doing so, the equipment EQ is monitored and controlled.
Therefore, according to the centralized monitoring and control system 1 of the present embodiment, even if a network failure or a server failure occurs, the failure can be quickly recovered by switching between the normal operation and the standby operation of the monitoring and control server device MSV. can do.
Further, according to the centralized monitoring control system 1 of the present embodiment, the regular operation and the standby operation of the monitoring control server device MSV are automatically switched, so that the system administrator can reduce the trouble of switching the operation by manual setting. Can be done. That is, according to the centralized monitoring and control system 1 of the present embodiment, the monitoring and control systems installed in each jurisdiction are integrated into a number of monitoring and control server device MSVs smaller than the number of jurisdictions, and the monitoring and control system is installed. Equipment EQ can be monitored and controlled independently of the (jurisdiction area). As a result, the centralized monitoring and control system 1 with high availability can be realized.

Further, the centralized monitoring control system 1 of the present embodiment switches between the regular equipment information storage unit IU and the emergency equipment information storage unit IF when the monitoring control server device MSV is on standby. For example, if switching is performed when the monitoring and control server device MSV is in regular use, the equipment information EI, which is the standard of operation, is changed in normal use. In this case, the transmission and reception of information between the monitoring and control server device MSV and the equipment EQ is normal. May not be done.
The centralized monitoring and control system 1 of the present embodiment switches between the regular equipment information storage unit IU and the emergency equipment information storage unit IF when the monitoring and control server device MSV is on standby. Therefore, the equipment information EI is not changed when the information is transmitted / received between the monitoring / control server device MSV for normal operation and the equipment EQ. As a result, the centralized monitoring and control system 1 of the present embodiment can prevent the information transmission / reception between the server device and the equipment EQ from being normally performed due to the indefinite transmission / reception destination.

Further, the monitoring control server device MSV of the centralized monitoring and control system 1 of the present embodiment includes a database (equipment information storage unit EM in this example) that stores power equipment information (equipment information EI in this example). Therefore, according to the centralized monitoring and control system 1 of the present embodiment, it is possible to reduce the cost associated with arranging the database for storing the power equipment information for each monitoring and control system.
